SIMON MIGNOLET insists Liverpool must remain calm and focussed ahead of the weekend's trip to Southampton and not allow criticism of the Reds' defensive vulnerability affect their last 11 Premier League matches.

The Reds' defensive frailties have come under increasing scrutiny after Sunday's 4-3 victory over Swansea at Anfield where Martin Skrtel produced a shaky display alongside Daniel Agger.

Liverpool have now conceded seven goals in their last three games and kept only two clean sheets in their last 11 matches, but Mignolet feels a composed approach will help the club achieve the best possible results in the final three months of the season.

"We are in a good position at the moment but with 11 games to go there are still a lot of things that can happen," he told the Liverpool Echo.
